Adobe Flash no longer supported after Dec. 2020. I have a Windows 10 installed, what about future updating? Any other taking its place? Some sites require a player for viewing ads, etc.
#1 After Dec 31st, Flash Player is dead.
#3 Not anymore because nobody will see them.
Flash content developers have had 3 years to prepare for this. If they didn't switch to new web technologies by now, they are already obsolete. This is just the final nail in the coffin.
